zynqmp_pinconf_cfg_set(9)

✨ zynqmp_pinconf_cfg_set(9) ✨

okay so bestie, welcome to the Kernel API Manual entry for zynqmp_pinconf_cfg_set — the little function that goes "yes ma'am" and actually pushes your pin config to the firmware 🎀

---

🌸 NAME 🌸

zynqmp_pinconf_cfg_set — sets the config you asked for on the pin. that's it. that's the whole job. and she does it flawlessly 💅

---

🦋 SYNOPSIS 🦋

int zynqmp_pinconf_cfg_set (struct pinctrl_dev *pctldev , unsigned int
pin , unsigned long *configs , unsigned int num_configs );

like, look at her. four args, returns an int, no drama ✨

---

💖 ARGUMENTS 💖

• pctldev — the pincontrol device pointer. your main character device, basically 👑
• pin — the pin number. which pin are we talking about, bestie? this one 📍
• configs — the configuration to set. the actual vibes we're applying 💫
• num_configs — how many configurations there are. gotta know how long the list is 🔢

---

🌈 DESCRIPTION 🌈

so what she does is: she loops through all of the configurations and calls the firmware API to set the requested configurations for the pin 🫶

that's the whole flow, no cap. loop, then firmware API, then you're done. it's giving "trust the process" ✨

---

⭐ RETURN ⭐

• 0 on success 🎉
• otherwise, an error error code 😭 (so like, always check, bestie)
